1 Claim.

The object of the invention is to provide a jar cap clamp sofa character that will make its application on any of the conventional jars possible with the minimum of time and skill on the part of the user; to provide a jar cap clamp that will make possible the supporting of the jar in inverted position after the lid has been clamped in place to determinewhether-there; has been a tight clamping indicated by the absence of leakage and this without risk of the jar being cracked by reason of being brought into contact with a relatively cold surface, such, for example, as a table top; to provide a clamp that will function effectively to retain in place the closure of a wide mouth jar; and generally to provide a device of the kind indicated which is of simple form' and susceptible of cheap manufacture.

With this object in view, the invention consists in a construction andcombination of parts of which a preferred embodiment is illustrated in the accompanying drawing, wherein:

Figure 1 is a perspective view illustrating the 1 upper end of a preserving jar showing the invention applied in operative position.

Figure 2 is a view similar to Figure 1 but showing the invention in its intermediate clamping position. it a Figure 3 is a central diametrical sectional view of a preserving jarequipped withthe invention but showing the latter in'inverted position to determine whether there is any leakage between relation to the neck andvhaving its extremities twisted together as indicated at 15. But'the neck wire is formed with spaced eyes '16; arranged in pairs on diametrically opposite sides of the jar.

With the neck wire or band the clamping bails are connected and each of these is formed from a wire strand bent to provide a straight bridge portionl'l connected by loops l8with the legs 19, the latter being twisted at an intermediate point to provide loops 20 which constitute feet bearing on top of the jar top 10. The free extremities of the legs are inturned, as indicated at 21, to pro vide pintles engaging in the eyes 16 ofthe neck wire or band. ,The pintle portionsof the legs are disposed under the flange bounding the jar mouth, sothat the pull of the clamping bails is against this flange and not against the neck wire eyes which merely function to attach the bails.

The clamping bails, of which there are two, are:

PA-TENT OFFICE v of identical form and when disposed in clamping position are retained in such by the latching bail 22 which is also formed from a single strand with the inturned extremities 23 engaged in the eyes 18 of one of the clamping bails, so as toprovide a pivotal connection between said clamping bail and the latching bail. The latching bail is also formed with a bridge, portion 24, with straight arm portions 25 and with sinuous arm portions 26, the arm portions 26 being bent'down to lie in a plane almost at rightangles to the plane of the major portion of the legs of the clamping bail. The arm portions 25 connect the bridge i I portion with the arm portions 26 but are arranged in planes which converge with the plane of the arm portions 26. The arm portions 26, by reason of their sinuous formation, have the spaced seats 2'7 formed in them,vthese seats receiving the bridge portion of one of the clamping bails '12. When those seats27 adjacent the arms 25 engage the bridge'portion 17, the clamping bails are not held as tightly against the jar top as when the bridge portion 1'7 is in the other seats 27. Thus two degrees of intensity are provided for retaining the jar cap in place and, after the cap has been attached, tests may be-made to determine whether there is any leak byinverting Iv I the jar asindicated in Figure "3, when the eye portions 18 of the clamping bail-becomeqfeet I. '35 -vated level above the supporting surfaceor. table.

which support the jar, when inverted,at.an ele- Thus, the jar is not quickly cooled, as when it is inverted with the cap or cover directly on the.

table or support. There is thus, in the use of the l device, no likelihood of the jar cracking by rea son of too quick cooling. Forming the"clamping bails with the inturned extremities 21; makes it v possible to quickly attach them after the neck .wire has been attached. Similarly, providing the latching bail with'the inturned extremities23 makes for quickly attaching it'to the eyes 18 of v one of the clamping bail members, leavingthe seats in the arms 26 to engage the bridge portion 17 of the other clamping bail.

The invention having been described; what is claimed as new and useful is: 1

A devicefor the purpose indicated comprising v a neck wire for attachment around the neck of a jar, clamping bails formed-peach of a single" i strand of wire terminally bent to'provide inwardly' extending extremities engagea'ble in eyes formed in the neck wire, and a latching bail also formed of a single strand of wire,the clamping bails being formed with intermediate bends providing eyes constituting feet for bearing contact with the cap of a jar, the clamping bails being further formed with a straight bridge portion and bends at the extremity thereof forming eyes,

.1;99:s,'942 i n a the latching bails having inturned extremities pivotally engaged with those eyes at the extremities of the bridge portion in one bail and v having downturned arms formed with spaced 9 seats for engagement with the bridge portion of the other bail. v
